SAW-SWAGING MACHINE Specification of Letters Patent.

Patented May 26, 1908.

Application filed October 4, 1906. Serial No. 337,491.

T 0 all whom it may concern:

Be it known that I, J osEPi-i O. FOX, a citi` zen of the United States of America, and a resident of the city of Seattle, in the county of King and State of Vashington, have invented certain new and useful Improvements in Saw-Swaging Machines, of which the following is a specification.

My invention has for its primary object, the provision of a machine of the above type which will be of improved and simplified construction.

With the above and other objects in view, to be referred to in the following description, the invention resides in the construction, parts and combinations of'parts hereinafter described and succinctly defined in the appended claims.

In the accompanying drawing, in which like numerals of reference indicate like parts throughout the several views: Figure 1 is a view in front elevation of my invention, parts being broken away. Fig. 2 is avertical section taken on line 2-2 of Fig. 1. Fig. 3 is a plan view, and Fig. 4 is a fragmentary side elevation.

Reference numeral 1 indicates a base formed of a single casting, and provided with an integral bracket 2 adapted to be engaged by suitable fastening means, as shown, for securing the device in position.

Base 1 is provided with a recess 3, extending inwardly from its forward edge and having its'mouth flared, as shown, whereby to facilitate the insertion of the saw to be swaged, and communicating with this recess 3, at its inner end portion is a horizontal opening 4 in which the die 5 is mounted to slide.

The forward end portion of die 5 is approXimately rectangular in cross section and has the beveled end 5, while the rear end portion of the die is circular in cross section and the end thereof affords a broad bearing for the adjusting screw 6.

Related to the forward end of the die is a cam 7 having a shoulder 7, the same being formed on a shaft 8 rotatably mounted in the base. The means now employed for rotating shaft 8 consists of a slotted arm 9 fixed thereon, a slotted lever 10 mounted to turn on a suitable pin or the like, as 11, xed to the base at a point below a horizontal line passing through shaft 8, and a bolt 12 having a shoulder 12 bearing on arm 9 and threaded end portions passing, one through the slot of arm 9 and the other through the slot of lever 10. On the projecting end portions of bolt 12 are nuts 12 adapted to be alternately tightened to hold the bolt to movement witheither arm 9 or lever 10, this depending on the movement desired to be imparted to arm 9 relative to that of the lever.

Reference numeral 14 indicates a fixed pin projecting into recess 3 above the cam 7 and coacting with another pin 15 which is slidably mounted and rejects into said recess from the opposite side thereof, for clamping the saw. A screw 16 is employed for adjusting pin 15. Screws 16 and 6 have their outer end portions provided with heads of suitable angular contour to permit of their being readily grasped by a wrench (indicated by dotted lines in Figs. 1 and 3) for operation thereof to effect the desired adjustment.

Reference numeral 17 indicates a gage for limiting the. movement of lever 10, this, as now considered embodying a plate formed integral with base 1 and provided'with a vertical series of openings 17 into which the stop 18, in the form of a pin, is adapted to be inserted.

In operation, arm 9 and die 5 are properly adjusted, then the saw tooth placed between the beveled end 5 `of the die and the cam 7 with the point resting against shoulder 7 of said cam. The saw is then clamped between pins 14 and 15 by adjusting screw 16 inwardly after which lever 10 is swung until it strikes stop 18, thereby turning cam 7 so that it swages the tooth against the bevel end of the die. To release the swaged tooth, lever 10 is swung back to its normal position and screw 16 adjusted outwardly.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States of America, is

1. In a saw swaging machine, a base, a die therein, a shaft in said base, a cam on the shaft coperating with said die, a hand lever pivoted to said base and formed with a longitudinal slot, an arm longitudinally slotted and connected to said shaft, a bolt having a central shoulder and threaded ends with said shoulder disposed between said lever and arm and its ends passing through said slots of the lever and arm so as to be capable of movement along the lengths of said slots, and nuts on the bolt ends to lock said bolt to either the lever or arm.

2. In a saw swaging machine, a base, a die therein, a shaft in said base, a vearn on the arm or lever and loosely connected to the shaft to coperate With said die, a hand other. 10

lever longitudinally slotted and pivoted to Signed at Seattle, Vashington this 17th said base, an arm longitudinally slotted and day oi September 1906.

Connected to said shaft, and means project; JOSEPH C. FOX. ing in said slots of the lever andV arrn capable Witnesses: of being moved along the lengths of said slots S. D. WINGATE,

and of being rigidly connected to either said STEPHEN A. BROOKS.
